PRESS FOR SOLING SHOES Erik Algot Hammarsjii, Stockholm, Sweden Application July 28, 1932, Serial No. 625,442 In Sweden May 18, 1931 19 Claims.

, The old practice of sewing or pegging shoes is fast being discarded in favor of cementing because of the advantages offered by this new method. Cementing is usually done by spreading the cement on the sole and then applying the sole to the insole of the shoe into which a last or like support has been previously inserted, and subjecting the shoe to pressure in a press for soling shoes, the sole being pressed against which may be easily and quickly adjusted to the shoe to hold the relatively thin welt portion fiat and in firm engagement with the edges of the sole and apply pressure thereon from above to counteract the curling or bending tendency due to pressure from below. A special feature lies in the combination of these clamps with the I press parts so that there is proper coordination in the application of pressure to the welt with the application of pressure to the shoe as a Whole.

The invention is hereinafter more fully described by reference to the accompanying drawings, in which- Figure 1 is a vertical section through a shoe press showing welt clamps made in accordance with my invention, the section being on the broken line I-l of Fig. 2;

Fig. 2 is a front View of the press, further illustrating the welt clamps;

Fig. 3 is a plan view, and 1 Figs. 4, 5, and 6 are side, front, and top views,

respectively, of the Welt clamps removed from the shoe.

3 The same reference numerals are applied to corresponding parts throughout the views.

Referring to Figs. 1 to 3, the press illustrated "comprises an arch or yoke l reaching over the 5 'erably of hollow rubber construction, filled with It is, therefore, the principal object of my invention to provide'welt clamps of a shoe, indicated at d, placed thereon for the application of pressure to the sole 5, it being understood that the sole is, of course, treated with cement before it is applied to the shoe. A last, indicated at 6, is put in the shoe covering substantially the entire bottom of the inside of the shoe. On this last is placed a presser foot I, and pressure is'applied to the last through the medium of the foot '3 by a screw 8 threaded in the arch i. Naturally, in this application of pressure to the shoe, the sole 5 is brought into solid engagement with the insole of the shoe throughout the entire area thereof. The fact that the welt portion 9 of the shoe projects marginally from the shoe and the cushion 3 yields under the application of pressure by the shoe results in the curling or bending upwardly of the welt, when nothing is provided to apply pressure thereto in a fashion corresponding to'the application of pressure to the shoe bottom by the last ii. The welt clamps ill of my invention are provided for the purpose of applying presure to the Welt to hold it flat and in firm engagement with the edges of the sole so that the sole is united to the Welt just as securely as it is to any other part of the insole. j

As shown in Figs. 4 to 6, the welt clamps ID are provided in a pair, one for engagement with the welt at the outer side of the shoe and the other at the inner side. Being made of thin sheet metal, they are flexible enough length-Wise to be easily conformed to the shape of the shoe. Two rods I 5, parallel to one another, provide adjustable spacing and connecting means for the clamps. Each of these rods has an end portion 52 bent downwardly at right angles and entered in registering holes in the opposite sides of the channel-shaped upper end portions I3 of the clamps, as shown in Fig. 5, for a pivotal connection. The other end of each rod is straight and projects through a hole in an inwardly inclined projecting lug on the portion it of the companion clamp for'a sliding frictional connection with the latter. In other words, each of the rods II has a pivotal connection at one end with one clamp and a sliding frictional connection near the other end with the other clamp. The fact that that portion of the clamp through which the straight end of the rod is inserted is bent inwardly causes the clamps to be locked releasably against movement away from one another when they have been pushed in against the 'sides'of the shoe. Each clamp has inwardly projecting teeth l4 formed on the lower edge thereof for engagement with the welt to press the same into firm engagement with the marginal edges of the sole. The advantage of having teeth instead of a continuous flange lies in the fact that the clamps are more easily flexed to conform to the shape of the shoe.

In operation, the clamps are adjusted with respect to one another to bring the teeth l4 into engagement with the welt along both sides of the shoe, and the operator is careful to have the crossrods II arranged so that they will be forced downwardly by the presser foot 1 at the same time that the presser foot applies pressure to the last 6 to force the shoe down upon the cushion 3. In that way, there is every assurance that the welt 9 will be kept flat and in firm engagement with the marginal portions of the sole 5, and the resulting cementing job will be uniformly good and there will be no danger of portions of the welt standing away from the sole.

What I claim is:
